When developing the line of MATHESON Select® Shielding Gases, we “threw out the book” on conventional shielding gas mixture composition. We studied ultra-high speed video of droplet formation and plasma stability. We studied weld consistency. We looked at weld cross-sections to observe weld depth, shape, porosity, and metallurgical characteristics.

The result is a line of welding shielding gases that helps you get better productivity and efficiency, while at the same time, achieving higher quality welding results.
